Abstract

PROBLEM TO BE SOLVED: To eliminate effects of noises due to electromagnetic wave generating in an uninterruptible power unit by providing an opening/closing metallic partition between the uninterruptible power unit and enclosure and shielding the electromagnetic waves generating in the uninterruptible power unit therewith. SOLUTION: Metallic partitions 9 and 12 for shielding electromagnetic waves are installed between an enclosure, such as a computer enclosure or a disk enclosure, etc., which is arranged on a free-access floor 6 within a computer room and an uninterruptible power unit, arranged on a free-access floor 14. Thus, since the partitions 9 and 12 are installed between the uninterruptible power unit and enclosure, such as a computer enclosure, a disk enclosure, etc., electromagnetic waves generated in the uninterruptible power unit can be shielded therewith, thereby eliminating noises due to electromagnetic waves generated from the uninterruptible power unit.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic noise suppression device, and more particularly to an electromagnetic noise suppression device and method for preventing the influence of noise on a computer system due to electromagnetic waves generated by an uninterruptible power supply.

[0002]

2. Description of the Related Art A layout of a conventional computer room will be described with reference to a plan view of FIG. As shown in FIG.
Inside, devices such as an uninterruptible power supply 2, a distribution board 3, a computer housing 4, and a disk housing 5 are arranged. That is, in these equipment arrangements, the uninterruptible power supply 2 is arranged at one corner in the computer room 1. A power distribution board 3 which receives an output of the uninterruptible power supply 2 as an input and is output to each device by dividing the power supply is arranged closest to the uninterruptible power supply 2. A computer housing 4 having an arithmetic function is arranged adjacent to the distribution board 3, and a disk housing 5 having a storage function is arranged next. The reason for arranging the devices in this order is to prevent as much as possible the effect of noise caused by electromagnetic waves generated in the uninterruptible power supply having forward conversion and reverse conversion.

[0003]

However, the above-described conventional method of arranging devices in a computer room cannot be applied to all computer rooms. For example, in the case of a building structure in which the distance between the disk housing 5 and the uninterruptible power supply 2 is not sufficient, or when the door of the computer housing 4 or the disk housing 5 is opened during operation of the computer system, the uninterruptible power supply 2 When the computer system may malfunction due to the influence of noise due to the generated electromagnetic waves, the conventional device arrangement method cannot be applied. Therefore, an alternative solution has been required.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electromagnetic noise suppression apparatus and method for preventing the influence of noise due to electromagnetic waves generated in an uninterruptible power supply.

[0005]

In order to achieve the above object, an electromagnetic noise suppression apparatus according to claim 1 of the present invention is a computer having an uninterruptible power supply, a computer housing, and a housing such as a disk housing. In the room, a metal partition that can be opened and closed is arranged between the uninterruptible power supply and the housing, and the metal partition is configured to shield electromagnetic waves generated from the uninterruptible power supply and the like. I do.

According to a second aspect of the present invention, each device housed in a housing such as a computer housing and a disk housing installed in the computer room by an electromagnetic wave generated from an uninterruptible power supply installed in the computer room. In the method for preventing an electromagnetic noise from malfunctioning, a metal partition is arranged between the uninterruptible power supply and the housing to shield electromagnetic waves generated from the uninterruptible power supply.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention.
(Corresponding to claim 2). In FIG.
Is a free access floor on which housings such as a computer housing 4 and a disk housing 5 are installed; 7 is a free access floor 6
8 is a ground floor, 9 is a metal partition for openable electromagnetic shielding installed on the free access floor 6, 10 is a metal mounting rail for a computer room ceiling, and 11 is free access. Mounting rail, 12 is an electromagnetic shielding metal partition between the free access floor 6 and the ground floor 8, 13 is an electric wire through hole, and 14 is a free access floor on which the uninterruptible power supply 2 is installed.

As described above, in the present embodiment, the housing such as the computer housing 4 and the disk housing 5 installed on the free access floor 6 in the computer room 1 and the free access floor 14 are installed. Between the uninterruptible power supply 2 and the electromagnetic shielding metal partitions 9 and 12 are installed. Therefore, during the operation of the computer system, the metal partition 9 is closed to form a flat plate, and when the computer system is stopped and inspected, the metal partition 9 is opened, so that an inspection work space can be secured, thereby facilitating the inspection work. .

Further, since the metal partitions 9 and 12 are arranged between the uninterruptible power supply 2 and a housing such as the computer housing 4 and the disk housing 5, electromagnetic waves generated from the uninterruptible power supply 2 are not affected. Since it is shielded, noise due to electromagnetic waves from the uninterruptible power supply 2 can be prevented. Furthermore, even when a computer room is provided in an existing building and the uninterruptible power supply cannot be installed on a floor different from the floor where the computer room is located or on a separate room, an installation environment equivalent to being installed in a separate room at low cost can be set. Further, when the CRT monitor is arranged with the uninterruptible power supply with the metal partition interposed, it is extremely effective against the fluctuation of the screen of the CRT monitor.

[0010]

As described above, the present invention (Claim 1)
According to the present invention, since the devices arranged in the computer room are electromagnetically shielded by the metal partition, noise due to electromagnetic waves from the uninterruptible power supply can be prevented. Further, even when a computer room is provided in an existing building and the uninterruptible power supply cannot be installed on a floor different from the computer room or in a separate room, an installation environment equivalent to that of another room can be set at low cost. Further, it is extremely effective for shaking the screen of the CRT monitor.
